SPECIFICATION forming part of Letters Patent No. 682,571, dated Setember 10, 1901.

Original application filed May 11, 1900, fierial No. 16,320r Divided andthis application filed October 8, 1900. Serial No. A

To all whom it may concern.-

Be it known that I, HENRY J. SAGE, of Beaver, in the county of Beaverand State of Pennsylvania, have invented a new and use- 5 fulImprovement in Apparatus for Bending Glass, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawing, forming part of this specification, in which thefigure is a side [0 elevation of my improved apparatus.

The shaping of glass by bending presents in many cases considerabledifficulty, especially in bending curved pieces of a large are. Forexample, a piece of glass equal 'to or 15 greater than thesemicircumference cannot be bent in a former all sides of which are inan arc of a circle, because the edges of the sheet when placed in theformer will overlap or pass beyond the same and the sheet will 20 notsettle down into the formerin the proper position when softened.

In the drawing, 2 represents the matrixblock, having a surface cavity.of the shape to be given to the glass sheet. This cavity 2 5 at the baseis circular; but at the upper portion 3 it extends outwardly or flareson planes more divergent than the sidewalls of the Gav- 'ity. The sheetof glass 4 when laid in the cavity rests upon the upper divergent sidewalls and is confined between the same, and 0 when it is heated it sinksdown into the matrix-cavity, as shown by full lines, producing a trueand shapely article.

I claim 1. Apparatus for bending glass, comprising 3 5 a matrix havingguiding-surfaces extending beyond the-matrix cavity, and formed inplanes more divergent than the walls of the matrix; substantially asdescribed.

2. Apparatus for bending glass comprising 46 v a matrix having aguiding-surface for the glass extending beyond the matrix-cavity andflaring outwardly therefrom on a line different from the curvature ofthe matrix-cavity;

substantially as described. 45 v In testimony whereof I have hereuntoset my hand. HENRY J. SAGE.
